I want an OpenGL applet but it keeps getting this error. How can I use ClassLoader to fix the permissions? The reason for an applet instead for webstart because I want to make online games for websites. Another reason I want an applet because I want my web pages interactive by putting multiple applets in one page. If possible, do not let the game display a security notice because is scary for most users because they think the security notice is similar to the dangerous ActiveX notices.

I haven't built any applets using JOGL but my understanding is that you need to both sign your applet (causing a security warning, etc. notice) as well as copy the JOGL jar file and native library into the user's JRE. This is why we recommend deploying JOGL applications via Java Web Start. Is there a compelling reason you can't use JWS but have to have an applet?

There is a reason because making a game in Java instead of C or C++ because it works in the browser, but software rendering is too slow at a high resolution. Flash and Shockwave are too slow to make online games.

Another reason is that people will get scared because JWS is similar to downloading freeware because it can contain viruses, spyware, adware, Trojan horses, bloatware, mess up the computer, and make the computer slower. When students are playing JWS games at school, teachers *MIGHT* think the JWS games contain viruses because it's not played in a browser, so they will block my game site, in which I doubt, because students might be blocked from installing Java 5.0, because most schools have Windows Netscape with IE 6.0 (and Microsoft Java Virual Machine, I guess), but if the Java version is outdated, unless they told the teachers, in which I doubt, because most Java applets still work on older versions, so teachers think there's no reason for installing a newer version that's slower at loading the applets because of the stupid Java Logo, that sometimes crashes IE and Firefox on Windows, especially if there is a missing a class or jar file, or sometimes clicking on it, that displays before it fully loads. I know how to turn off the logo by inserting some params, but it's the other applets. I think some administrators school computers that are good at computers that knows many things other than Microsoft Windows are smart enough to install Java 5.0, and the administrator of some school computers are not in the same school every day, if the computer teachers don't even these have permissions, but I doubt computer teachers don't have these permissions.

[size=12pt]but still, how do I sign my applet to fix the errors? I tried to read the instructions on how to sign it but it didn't work.[/size]

I know they would downloaded the newer version, and has been downloaded, because most people that play on any game site downloaded the latest versions Flash player and Shockwave player. Most people play game at home, because almost ALL SCHOOLS BLOCK game sites anyway.

Java 1.1 is NOT recommended because I can just use <object> tag for IE to check the version and download the newer version so it would show an ActiveX notice to install a newer version of Java similar to Flash and Shockwave installations.

You can use jarsigner.exe (which comes with the JDK). Unless you actually pay for a real certificate, you will have to generate one yourself, which is effectively "untrusted" and the user will be asked to trust you.

After months of struggling to make my own Java games out of JOGL, I've been given up, wasting time, and debugging my source codes. I've been frustrated and guilty that I didn't make any of my own Java games. Will software rendering make the game's FPS reasonable at a 512x512? Can you show me how sign my JOGL applet correctly? Are there any example source codes?

Maybe you should try to start with a WebStart version. Not because you want to use WebStart, but because it has similair signing techniques and with WebStart it's been proven to work, so lots of people can help you. When you have the WebStart version running, with help of us, you can try to make the next step yourself, which should be much less complex by then.
